Sounds interesting...I shall read this later too!
I haven't used spotify or pandora much, and haven't used rdio at all...used to be because I preferred listening to my CDs than new music (or maybe because I had no internet, back in the dark days, and buying new CDs all the time was too expensive)...... Since internet became as good as free, I love exploring new music...because I can...but I tend to do it all on youtube...
The number of ads on YouTube is getting more and more. I guess money has to be made. But I do find it a bit pointless where it's the same flippin ad before every video...even when you're just replaying the same video.
It's only recently that I've used soundcloud to listen to anything other than all you lot's lovely sounds...
Anyway, I haven't read the blog yet but I shall later
